Claims.

This invention relates to improvements in spray containers.

It is an object of this invention to provide a construction of spray container whereby prac- 5 ,tically the entire contents of the container can be ejected as a spray from the container.

Other objects will be apparent from the specification and from the accompanying drawing in which latterv Fig. 1 is a perspective view of a spray container having the improvements thereon;

Fig. 2 is a transverse sectional view taken along the line IIII of Fig. 1;

,Fig. 3 is a transverse sectional view of a modified form of the invention;

Fig. 4 is a transverse sectional view taken along the line IV-IV of Fig. 3; and

Fig, 5 is a transverse sectional view through still another modified form of the invention. Referring particularly to Figs. 1 and 2, reference numeral l designates a container having flexible side walls which can be compressed by the fingers of the operative to exert pressure upon the contents of the container, and which will 2 6 assume its original shape when the pressure is released. The container may advantageously be. pressed with a ribbed design to impart extra springiness to the walls of the container. The container is provided with an opening 2 in its end wall 3. A nozzle 6 protrudes outwardly from the end wall 3, the annular base of the nozzle being disposed upon the wall 3 surrounding the opening 2. The nozzle 6 is provided with screw threads for engagement with screw threads of a removable closure 8 which covers the open outer end of the nozzle 6. A sealing disc In extends transversely across the open end of the nozzle 6 between the open end and the closure 8 and is held in position by means of a ring ll of cork or other suitable material. The closure 8 is provided with a spray hole l2 which opens into the nozzle.

The device can be utilized for spraying liquids, for purposes for which efi'icient atomization is not required, such as for spraying liquids to be used for window cleaning. The closure 8 is unscrewed from the nozzle 6 and the seal I0 is removed. The closure 8 is then replaced upon the nozzle. The liquid is ejected from the spray con- 60 tainer by tilting said container until liquid covers the opening [2 and pressing the flexible side walls of the container. If desired, the spray hole l2 can be formed in the closure 8 before placing the closure in position upon the nozzle or after 55 the container has been sealed.

Referring particularly to Figs. 3 and 4, a modified form of the invention is shown in which the end wall 3 is provided with an opening 15 which in the preferred form is in the shape of a half moon in top plan view. A nozzle 11 protrudes 5 from the wall 3, the nozzle base and the nozzle being disposed upon the wall 3 surrounding and. larger than the opening I5, leaving a portion of the wall 3 interposed between the nozzle and the interior of the container i to form a dam I9. 10 This portion of the wall 3 constitutes a baffle plate. The nozzle ll is provided with screw threads adapted to be engaged by the threaded side walls of the closure 2!. The nozzle ll, closure 2| and dam l9 cooperate to form a pocket 15 laterally of the opening 15 to accumulate liquid flowing through the opening i5 into the nozzle upon tilting the container I. The closure 2| is provided with a spray hole 22 which opens from the pocket below the level of the dam when 20 the nozzle is in substantially horizontal position and through which the liquid is ejected when pressure is applied to the contents of the pocket by compressing the side walls of the container. The pocket becomes filled by tilting the container 25 forward sufficiently before pointing it in the spraying position. Thus the last fraction of the contents of the container can be ejected without tilting the container beyond the horizontal position. 30

Referring particularly to Fig. 5. of the drawing,

a modified form of the invention is shown in which a nozzle 25 protrudes from the end wall 3 of the container l. An auxiliary reservoir extends into the nozzle. The auxiliary reservoir 35 comprises a cup shaped member 21, the open end 28 of which opens outwardly through the open end of the nozzle and is provided with a flanged portion 29 which seats upon the outer end of the nozzle. The cup shaped member is secured in position by means or a closure 30 and cork ring iii. A side wall of the cup shaped member 21 is provided with a hole 32 which communicates with the reservoir and with the interior of the container 1. A spray tube 33 passes through the closure 30 and opens at its inner end adjacent the bottom of the cup shaped member 21. The cup shaped member 27 is assembled in position in the nozzle after the container 1 has been filled with the liquid.

Various changes may be made within the scope of the appended claims in which it is desired to claim all novelty inherent in the invention as broadly as the prior art permits.

I claim:

1. A device for spraying liquid, comprising a container imperforate except for an opening in one wall, a nozzle, coinciding with the opening and communicating with the container therethrough, protruding from a wall of the container, adapted to permit filling of the container and to permit flow of liquid 'from the container into the nozzle when the container is inverted, the outlet end of the nozzle having a spray hole of lesser size than the opening, and a bafiie plate extending transversely across a portion of the nozzle .to function as a dam to trap a portion of the liquid and prevent its backward flow from the nozzle into the container when the container is restored to a substantially horizontal position, the spray hole being below the level of the dam when the nozzle is restored to a substantially horizontal position whereby the trapped liquid in the nozzle can be ejected from the nozzle through the spray hole by pressure applied to the contents of the container.

2. A device for spraying liquid, comprising a container imperforate except for an opening in one wall, a nozzle, coinciding with the opening and communicating with the container therethrough, protruding from a wall of the container, adapted to permit filling of the container and to permit flow of liquid from the container into the nozzle when the container is inverted, the outlet end of the nozzle having a spray hole of lesser size than the opening, the opening being of lesser diameter than the base of nozzle whereby a portion of the wall functions as a dam to trap a portion of the liquid and prevent its backward flow from the nozzle into the container when the container is restored to a substantially horizontal position whereby the trapped liquid can be ejected from the nozzle through the spray hole by pressure applied to the contents of the container.

3. A device for spraying liquid, comprising a container imperforate except for an opening in one wall, a nozzle, coinciding with the opening and. communicating with the container therethrough, protruding from a wall of the container,

adapted to permit filling of the container and to permit flow of liquid from the container into the nozzle when the container is inverted, the

outlet end of the nozzle having a spray hole of lesser size than the opening, the opening being of lesser diameter than'the base of the'nozzle and adjoining one side wall of the nozzle whereby a portion of the container wall functions as a dam to trap a portion of the liquid and prevent its backward flow from the nozzle into the container when the container is restored to a substantially horizontal position, the spray hole being offset with respect to the opening whereby the trapped liquid in the nozzle can be ejected from the nozzle through the spray hole by pressure applied to the contents of the container.

4. A device for spraying liquid, comprising a container imperforate except for an opening in one wall, a nozzle, coinciding with the opening and communicating with the container therethrough, protruding from a wall of the container, adapted to permit filling of the container and to permit flow of liquid from the container into the nozzle when the container is inverted, the outlet end of the nozzle having a spray hole of lesser size than the opening, the opening being of lesser diameter than the base of the nozzle whereby a portion of the wall functions as a dam to trap a portion of the liquid and prevent its backward flow from the nozzle into the container when the container is restored to a substantially horizontal position, the spray hole being offset with respect to the opening and below the level I the annular base of the nozzle being disposed,

upon the wall of the container surrounding and larger than the opening whereby a pocket is formed laterally of the opening to accumulate liquid flowing through the opening into the nozzle when the container is inverted, the closure hav-- ing a spray hole opening from the pocket through which the liquid is ejected when pressure is applied to the contents of the container.
